APPARATUS FOR SUPPLYINGABRADING AND POLISHING MATERIAL TO CUTTING ANDPOLISHING TOOL S.

SPECIFICATION formingpart of Letters Patent N0. 283,273, dated August14, 1883,

Application filed June 23, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN S. OConnon, of

White Mills, in the county of Wayne and State of Pennsylvania, haveinvented a new and useful Improvement in Apparatus for SupplyingAbrading and Polishing Material to Cutting and Polishing Tools; and Ido. hereby declare that the following is a full, clear, and exactdescription of the same. In the process of manufacturing line outglassware the operations of cutting and p olishing are performed by arevolving wheel run at high speed, in contact with which the glassarticle is held by the operator. In the process of polishing, theperiphery of the wheel must be constantly supplied with polishingmaterial, as otherwise the heat generated by the friction would crackthe glass and ruin the articles. The method commonly employedinglass-works is to have the polishingpaste supplied to the wheel by a boywith a brush, under the supervision of the cutter. This method, besidesentailing the expense of an additional operative, is objectionable,because carelessness or inattentionon the part of the boy may ruinvaluable articles of glassware, and a certain percentage of loss fromthis cause occurs in all glass-factories.

My invention relates to means for supplying polishing material to thepolishing-tool; and its object'is to apply such material by means of aconnected automatic mechanism under control of the operator.

My invention consists, first, in combining with the polishing-tool andpositively-operated pastesupplying devices means under control of theworkman for throwing such devices out of and into gear with thedrivingpower; further, in combining with the polishing-tool abrushrevolving so as to come in contact therewith, and a supply'or receptaclefor polishing-paste or other material; further, and finally, in thepeculiar and improved construction of the apparatus and its variousparts, as fully hereinafter described and claimed.

In the drawings, Figure 1 is a cross-section through the paste-receiver,showing the driving-shaft andpolishing or cutting tool in elevation.Fig. 2 is a perspective of the pasteapplylng mechanism upon a largerscale. Fi 3 1s a slmllar view of the whole apparatus.

In Fig. 1, A represents a frame-work of any suitable kind, and B is ashaft running in adjustable boxes at a. Upon this shaft is mounted thepolishing or cutting wheel 0, of ordinary construction. The shaft andwheel are driven by a belt from the pulley Z1 to any suitable power.Upon two of the cross-beams of the frame is supported a box, D,withinwhich is held a box, D. The box I) is movable within the box D,and is made water-tight to hold the polis'hingpaste.

The devices for applying thepaste to the wheel are shown in detail inFig. 2.

F represents a standard composed of arms ff, having set-screws forattachment to asupport. Formed with this standard areupwardly-projecting arms G G, the top of each of which is flattened andformed into a half bearing for the transverse shaft H. The bearings arecompleted by boxes g 1/. Running loosely on the shalt H is acone-pulley, I, which is connected by a round belt, 71 to adrivingshaft. (Not here shown.) Upon one side of the pulley is a flangedor grooved boss, The box r/ is extended to form a plate, 7', upon whichslides a bar, is, passing through a guide, Z. The bar 7.: has a finger,m, which engages with the flange in the boss 2', and such bar I; ismoved longitudinally by a pivoted handlever, J. Uponthe opposite side ofthe pulley I is secured one half of a. toothed boxclutch, K. Theopposite half, K, is keyed upon the shaft H just within the bearings. Asthe clutch K revolves constantly with the pulley I, it is clear that themovement of such pulley may be communicated to the shaft by sliding thepulley on the shaft and locking the clutches. The sh aft H is extendedbeyond the bearing 9, and upon it is adjustably secured, bya set-screw,n, a holder, L. In this holder is adjustably secured the handle of abrush, M, the construction allowing the brush to be adjusted bothvertically and laterally. The brush will thus revolve with the shaft orremain stationary, according to the position of the clutches.

This apparatus, as thus described, is mounted upon the edge of the boxD, as shown in Fig. 3, and the inner box partly filled with thepolishing-paste. The brushis so adjusted that it will dip into the pasteat each revolution, and when in gear will also come in contact with thepolishing-wheel, keeping it eonstantly supplied with polishing material,without any attention or care on the part of the operator. As eacharticle is finished, or at will, it is an easy matter to move the leverand disengage the clutches, when the revolution of the shaft and brushwill cease. The brush ordinarily revolves at a speed of sixtyrevolutions per minute.

Having described my invention, I claim-- 1. Combined with a cutting orpolishing tool, a device for supplying polishing material to such tool,mechanism for operating such device, and means under control of theoperator for throwing such device into and out of gear with the drivingmechanism.

2. Combined with a polishing-tool, a reservoir of polishing material anda revolving brush, operated by mechanism substantially as described, soas to supply the tool with pol ishing material at intervals.

3. Combined with a polishing-tool reservoir to contain polishingmaterial, avertically and laterally adjust-able brush, and mechanism,substantially as described, for causing such brush to revolve.

4. The shaft H, in combination with the loose sliding pulley I, thelocking-clutch, the revolving brush, the polishing-paste receptaele, andthe polishing wheel or tool.

5. The shaft H, l'oose pulley I, having grooved boss, the sliding barand operatinglever, the clutches K K, and the brush and polishing-tool.

In testimony whereofI have signed my name to this specification in thepresence oftwo subscribing witnesses.

JOHN S. O CONNOR.
